Mental health disorders are among the most common health conditions in the United States. Traditional clinical treatments rely on psychiatric counseling and, in many cases, prescription medications. We propose an innovative model, Interventional Mental Health, which employs a combination of modalities through a multifaceted approach to treat conditions that have exhibited limited responsiveness to traditional methods and individuals afflicted with multiple comorbidities simultaneously.

Cardiovascular disease (CVD) accounts for more than 50% of deaths among patients with end-stage kidney disease (ESKD). Approximately 40-50% of ESKD patients have clinically significant coronary artery disease (CAD) due to atherosclerosis which accounts for a significant proportion of CVD risk. However, other CVD pathologies including myocardial fibrosis, vascular calcification and arterial stiffening play important contributory roles.

Taxane-based chemotherapy regimens are in widespread use as standard of care treatment for patients with early breast cancer, though rarely its use can be complicated by taxane-induced pneumonitis (TIP). While breast cancer is the most diagnosed cancer in women worldwide, TIP remains under-described in this setting. Key questions relate to its incidence, diagnosis and management, potential predictive biomarkers, and the balance between this life-threatening toxicity and curatively intended treatment.

Systemic treatment of hormone receptor-positive (HR+) breast cancer is undergoing a renaissance, with a number of targeted therapies including CDK4/6, mTOR, and PI3K inhibitors now approved for use in combination with endocrine therapies. The increased use of targeted therapies has changed the natural history of HR+ breast cancers, with the emergence of new escape mechanisms leading to the inevitable progression of disease in patients with advanced cancers. The identification of new predictive and pharmacodynamic biomarkers to current standard-of-care therapies and discovery of new therapies is an evolving and urgent clinical challenge in this setting.

Since its discovery in 2007, we have seen the lives of patients diagnosed with advanced anaplastic lymphoma kinase (ALK)-rearranged non-small cell lung cancers (NSCLC) transform with the advent of molecular therapies with first-, second-, and third-generation ALK inhibitors now available in the clinic. Despite great gains in patient survival now measured in years and preserved quality of life with targeted therapies, drug resistance is unfortunately inevitably encountered in this rare and unique molecular subset of lung cancer, and patients will eventually succumb to the disease. As these patients are often young, fit, and never smokers, the clinical and scientific communities have aligned to expedite drug development and access.

Introduction: Studies of bevacizumab and pembrolizumab in the treatment of malignant pleural mesothelioma suggest anticancer efficacy; clinical trial populations are not reflective of real-world patients. We aimed to determine the proportion of real-world patients who would be eligible for trials, identify patients who participated in clinical trials, and examine treatment and outcome data.

Patients And Methods: Consecutive patients with unresectable malignant pleural mesothelioma seen at our center from January 2012 to July 2018 were assessed with regards to their eligibility for Mesothelioma Avastin Cisplatin Study (MAPS) and KEYNOTE-028 clinical trials.

A small proportion of patients with malignant pleural mesothelioma (MPM) achieve pathological complete response (CR) following treatment with current practice induction chemotherapy. Our analysis of 58 patients with MPM treated with platinum-based chemotherapy showed 4 patients (7%) attained pathological CR at subsequent extrapleural pneumonectomy (EPP). Patient and tumour factors such as age, gender, smoking habit, histological subtype, and clinical stage were not found to be associated with pathological CR.

The resurgent component of voltage-gated Na (Nav) currents, I, has been suggested to provide the depolarizing drive for high-frequency firing and to be generated by voltage-dependent Nav channel block (at depolarized potentials) and unblock (at hyperpolarized potentials) by the accessory Navβ4 subunit. To test these hypotheses, we examined the effects of the targeted deletion of Scn4b (Navβ4) on I and on repetitive firing in cerebellar Purkinje neurons. We show here that Scn4b animals have deficits in motor coordination and balance and that firing rates in Scn4b Purkinje neurons are markedly attenuated.

Endoscopic imaging using optical coherence tomography (OCT) has been demonstrated as clinically useful in the assessment of human airways. These airways have a complex 3D structure, bending, tapering and bifurcating. Previously published 3D OCT reconstructions have not accounted for changes in the orientation and trajectory of the endoscopic probe as it moves through the airway during imaging.
